Taking a life-course perspective, we explored the sense of parenting efficacy during the pregnancy-postpartum transition among a group under-represented in much of adult developmental research, minority women. Our intent was to describe the women's report of parenting competency in a major life transition occurring within the context of an impoverished urban environment. We also explored associations with depression, social support, and life events. One hundred and eighty-two African-American and Hispanic mothers at community health centers in low-income urban areas completed measures early in the third trimester and again at 3 months postpartum. Across time, the levels of reported parental efficacy and satisfaction increased while depressive symptoms decreased. Negative life events and levels of depressive symptomatology differentially influenced women's experience of parenting satisfaction and efficacy feelings before and after their babies were born.  相似文献

Little is known about what additional services youth receive while they reside in out-of-home treatment settings. However, such information may be crucial for explaining effectiveness and variation in outcomes for youth in such settings. Our research examines patterns of multi-sector service use for youth in two settings—Therapeutic Foster Care and group homes. Data come from in-person interviews with Treatment Foster Parents and Group Home Staff for a NC state-wide sample of youth with psychiatric disorders and aggressive behavior. Findings indicated high rates of service use by youth in both settings. Analyses indicated significant differences in service types used by youth in each setting, yet similar volume of service use between settings. Clinical and demographic factors did not significantly influence types of services received. Differences in service patterns between the two groups indicated that youth in TFC were more likely to receive community-based, individualized services while youth in group homes were more likely to receive more restrictive services.  相似文献

We examined child psychiatric diagnoses, behavioral problems, overall symptom impairment, global psychological functioning, intellectual ability, and adaptive behavior in 83 sibling pairs whose mothers were diagnosed with a serious mental disorder. Sibling pairs were assessed for the extent to which they converged on the presence or absence of risk on each adverse outcome and then examined under conditions of high vs. low/moderate family stress. Consistent with the study hypotheses, we found that on each outcome assessed there was evidence for sibling convergence of risk. In addition, family stress was found to significantly moderate sibling risk convergence. The results are discussed in terms of their implications for understanding sibling convergence of risk in these families and for clinical and preventive intervention.  相似文献

In this investigation, we evaluated the effectiveness of surface electromyography (EMG) biofeedback to treat paradoxical vocal fold motion in a 16-year-old girl. EMG biofeedback training occurred once per week over the course of 10 weeks. In a changing criterion design, muscle tension showed systematic changes that corresponded with changes in the criterion. Overall, baseline muscle tension levels were reduced over 60%, with corresponding reductions in episodes of respiratory distress and chest pain. Subjective reports by the patient and the patient's mother indicated improvements in school attendance and overall adaptive functioning.  相似文献

For decades, suicide rates among minority African American and Latino young people have been stable and, when compared with Whites, relatively low. This is no longer the case, underscoring the need for documenting and understanding the problem of suicidality in this population. We report on the prevalence and predictors of suicidality among 879 urban adolescents in the Reach for Health study. All youth resided in economically disadvantaged neighborhoods; 69% were African American, 16% Latino, and 15% reported mixed or other ethnicity. In the past year, 15% had seriously considered suicide; 13% had made a suicide plan, 11% had attempted suicide at least once, and 4% reported multiple attempts. Risk factors significantly related to suicidal ideation are being female, having basic needs unmet, engaging in same-gender sex, and depression. Resiliency factors include family closeness and, marginally, religiosity. Risk factors related to reports of suicide attempts are being female, being Hispanic, and depression; family closeness is strong resiliency factor. Family composition, ethnic identity, coping style, peer support, and school attachment are not significant correlates of suicidal ideation or attempts.  相似文献

The purpose of this paper is to describe the implementation of a school-based trauma-specific mental health program in New York City following the terrorist attacks on September 11, 2001. This program aimed to serve children most at risk for developing mental health problems as a result of physical proximity (e.g., evacuation from schools surrounding the World Trade Center) to the trauma. As we present the components of the program, we will review the literature that guided our decision making. The ongoing struggle between searching for answers from established science and immediate needs in a crisis is highlighted. Lastly, a discussion of the lessons learned and recommended next steps is presented.  相似文献

Two adults with mental retardation demonstrated the recombination of within-syllable units (onsets and rimes) using a spoken-to-printed-word matching-to-sample (MTS) procedure. Further testing with 1 participant showed comprehension of the printed words. Printed-word naming was minimal before, but greater after, comprehension tests. The findings suggest that these procedures hold promise for further basic and applied analyses of word-attack skills.  相似文献

Mental health professionals' attitudes towards deaf people were examined in relation to their previous contact with deaf people and their knowledge of deafness. Data were gathered regarding different aspects of contact, including the number and type of relationships participants had had with deaf people. A cognitive-processing theory of attitude change following contact (Rothbart & John, 1985) was explored. Knowledge of deafness did not correlate with attitudes towards deaf people but a relationship was found between the amount of contact that professionals had with deaf people of equal or higher status and more positive attitudes.  相似文献

Background: Religious and spiritual beliefs and practices are common among medical inpatients, and may impact length of hospital stay (LOS) and other health services (HSU) during hospitalization. Methods: 812 consecutively admitted patients age 50 or over to Duke University Medical Center were assessed. Measures of religiousness and spirituality included religious TV/radio (RTV), self-rated religiousness (SRR), observer-rated spirituality (ORS), and daily spiritual experiences (DSE). The primary outcome was LOS. Results: RTV and SRR predicted longer LOS, whereas ORS and DSE predicted shorter LOS (p 0.05). Effects of RTV onLOS were stronger among women, but explained by worse health status. The effects of DSE on LOS were stronger among non-whites. Among those reporting high DSE, diagnostic tests and total procedures also tended to be less common. Conclusions: Religious activities, attitudes, and spiritual experiences are weak predictors of LOS and HSU during hospitalization. Whether the prediction is positive or negative depends on the religious or spiritual characteristic.  相似文献
